Differentiation of Haemophilus species
Microring®XV
Cat. #24644 (50 rings/pkg)
Microring®XV is a paper ring used in Haemophilus identification. It comes complete with individual printed tips containing haemin
(X-factor) and nicotinamide adenine dinucleotide-NAD (V-factor) or X+V factor. This ring differentiates Haemophilus species on the
basis of growth requirements for X and V factors and can be identified by their growth patterns close to the tips. V-tip also contains
δ-aminolaevulinic acid (ALA) for Porphyrin test. (The porphyrin test is best performed at the start when the ring is laid on the plate
prior to incubation. Using a loop take a sample of the test organism from a growing culture and spread lightly over the V-tip.
Non-haemin requiring species will cause an orange-red glow to be seen from the V-tip.)
Procedure
1. Spread sample of the test organism onto an agar plate of Tryptone Soy Agar or Columbia Agar (without blood).
2. Using sterile forceps, carefully place Microring®XV in the center of the plate. Press each tip gently to ensure contact with surface.
3. Incubate plate overnight at 37° C.
4. Following incubation, growth patterns around each tip are read and used to identify the organism.
X=Haemin V = NAD and δ-aminolaevulinic acid (ALA) XV = Haemin and NAD NG = No growth G = Zone of growth

Procedure
1. Spread sample of test organism onto a plate containing anaerobic agar.
2. Using sterile forceps, carefully place Microring®AN in the center of the plate.
Press each tip gently to ensure contact with surface.
3. Incubate for 24-48 hours at 35-37° C under anaerobic conditions.
4. Following incubation, growth patterns around each tip are read and used
to identify the organism. Zone diameters of 15mm or greater are considerd
susceptible, while those less than 15mm are regarded as resistant.

Microring®AN is a filter paper ring used for the identification of Non-sporing Anaerobes. It has 6 tips which are impregnated with a
range of antibiotics for the identification of species of anaerobic Gram-negative bacilli and can distinguish Gram-positive cocci from
Gram-negative cocci. Gram-negative anaerobic rods are found in more than half of clinical specimens containing anaerobes. Although
difficult to perform precise identifications, in practice most groups can be presumptively identified from their antibiotic susceptibility
profile, which is the basis of the Microring®AN test scheme.

Microring®AC is a filter paper ring used for the identification of Gram-positive anaerobic cocci and some microaerophilic cocci. It has 3
individual printed tips containing various antimicrobial reagents. The resistance or sensitivity patterns can be used to help identify
anaerobic cocci. In particular, P. anaerobius can be readily picked out by it’s sensitivity to SPS and P. magnus can be distinguished
from P. micros by its resistance to Novobiocin.

Microring®GVis a filter paper ring used for identification of Gardnerella vaginalis. The ring comes complete with 4 individual printed
tips containing various antimicrobial reagents. Each tip of the ring contains one of the following reagents; MTZ (metronidazole), TRM
(trimethoprim), STZ (sulphathiazole), and BIL, (bile salt). Each tip performs as a single identification disc because of an isolating
hydrophobic barrier. On blood agar, Gardnerella is identified by sensitivity to 3 designated tips and resistance to 1 tip.

Microring®YTis a filter paper ring used for the identification of clinically important yeasts, especially Candida species. Microring®YT
uses the organism’s profile of susceptibilities to a small range of reagents as the basis of identification.
Microring®YT carries 6 tips impregnated with a range of dyes and antifungal reagents. Each tip acts like an individual disc because
of the isolating hydrophobic barrier. Following overnight incubation, the resistance/sensitivity results of the individual tips are used
to produce a 6-figure code which is matched against a database to give the identity of the yeast.
